Filter by:The purpose of this study is to explore the pathogenes, clinical characteristics, laboratory and histological examination results, treatment and prognosis of autoimmune hepatitis(AIH). At phase 1, the investigators focus on studying of the clinical characteristics of acute autoimmune hepatitis, and then will study the difference about treatment effects between acute autoimmune hepatitis and chronic AIH. Morever, the investigators have noticed that drug induced AIH have some special characteristics that may be beneficial to distinguish it with durg induced liver disease. Therefore the investigators will do some studies about drug induced AIH or other disease which maybe related to the onset of AIH.
Biochemical response of primary biliary cholangitis-autoimmune hepatitis overlap syndrome induced by ursodeoxycholic acid only or combination therapy of immunosuppressive agents
An open-label,pilot study to evaluate the efficacy and safety of plasma exchange combination of immunosuppressive regimens, for the remission of autoimmune hepatitis (AIH).
Autoimmune hepatitis (AIH) is characterized by chronic inflammation of the liver, interface hepatitis, hypergammaglobulinemia, and the presence of autoantibodies. Disease presentation is varied but typically is based on characteristic aminotransferase elevations, histological abnormalities, elevated levels of serum globulins, and the presence of one or more autoantibodies. Two types of juvenile AIH have been identified according to seropositivity for smooth muscle and /or antinuclear antibody (AIH type 1) or liver kidney microsomal antibody (AIH type 2). Standard therapy in clinic consists of a combination of corticosteroids and azathioprine, which displays the efficacy in 80% of patients. However, 7% of patients deteriorate despite compliance with the standard corticosteroid regiments (treatment failure),13% of patients improve but not to a degree that satisfies remission criteria (incomplete response), 13% of patients develop serious drug-induced complications, and 50%-86% of patients will relapse after drug withdrawal. These serious drawbacks counterbalance the benefits of conventional therapy, and they are compelling reasons to refine current treatment strategies and pursue alternative therapies. UC-MSC has been the application for the treatment of several severe autoimmune diseases, such as immune thrombocytopenia, systemic lupus erythematosus, and therapy-resistant rheumatoid arthritis. In this study, the safety and efficacy of UC-MSC transplantation for AIH patients will be evaluated.
The purpose of this research is to study body materials like blood proteins as well as white blood cell and liver cellular RNA in individuals with liver diseases such as chronic viral hepatitis with or without hepatoma and autoimmune liver disease. Presently it is not understood how infection with chronic viral hepatitis or autoimmune liver disease damages the liver. This research study enroll patients with either chronic viral hepatitis with or without hepatoma or autoimmune liver disease. The purpose of this study is to find the genes that are expressed in both the circulating white blood cells and the liver of patients with varying degrees of liver damage of different causes. Genes are biological messengers some of which determine how the body responds to injury. We anticipate that results from Differential Gene Expression (DGE) analysis will allow us to make predictions about likelihood of disease progression and/or response to treatment. In addition we will test the blood for markers of injury. The blood collected will be prepared differently from the liver tissue. We will use technologies to express pure proteins and then we will investigate the functions of these proteins. Nearly all drugs act on proteins, not genes, so understanding proteins is the key to really effective new medicines. Similarly the first signs of ill health appear in changes to the body’s blood proteins, making them the most sensitive diagnostic indicators. The studies we plan are called proteomics. We will later correlate the patterns of gene expression in both circulating white blood cells and the liver tissue with clinical outcome and patterns of proteins measured in blood and we hope to gain an understanding of how the disease process occurs, which may in turn help us to make more precise diagnoses and develop new forms of treatment. These techniques that we use are still experimental and so we do not yet know if they will be helpful in monitoring changes which may help us to predict the potential severity of your liver disease or even if they can be used to indicate who will best respond to treatment.
